Moving branch points in the $j$ plane are investigated on the basis of analysis of multiparticle terms of the unitarity condition in the $t$ channel. A definite assumption about the form of an analytic continuation of these terms into complex $j$ is used. It is shown that in this case in the $j$ pla... View More
